SUPPLEMENTAL TIRE FOR VEHICLE-WHEELS- i No. 824,240.

Specification of Letters Patent.

Application filed. March 80, 1906. Serial No. 308.832. r c

To all whom it may concern:

Be it known that I, CHARLES H. Goon- MAN, a citizen of the United States, residin at Bucyrus, in the county of Crawford and State of Ohio, have invented new and useful Improvements in Sup lemental Tires for Vehicle-Wheels, of which the following is a specification.

My invention relates to certain new and useful improvements in supplemental flanged tires adapted to removably fit over the ordinary tire of the wheel ofan automobile or other vehicle, whereby the vehicle is readily converted from the ordinary road-machine to one that is capable of being pro elled or otherwise operated over the rails o a steam or, other railway; and my invention consists of the parts and the constructions and combinations of parts, which I will hereinafter describe and claim.

The essential object of my invention is to provide a comparatively simple and inexpensive supplemental flanged rim which is preferably made of metal and which is capable of being readily applied to the ordinary pneumatic, cushion, or other tires of a motor-vehicle or the like, whereby the vehicle may be quickly converted into a machine which is capable of fitting and being run over the rails of a railroad-track for the purpose of quick transit in reaching a point on the line where a wreck or accident has occurred and for inspection of the line and such other purposes as a vehicle of this character might be used to advantage.

In the accompanying drawings, forming part of this specification, and in which similar characters of reference indicate like arts in the several views, Figure 1 is a side e evation of a vehicle-wheel with my supplemental rim applied thereto. Fig. 2 is a sectional view of the same on the line w a; of Fig. 1. Fig. 3 is an enlarged sectional perspective of a portion of the wheel. Figs. 4 and 5 are modifications to be referred to.

As before stated, my invention is to be considered primarily as in the nature of an attachment to the wheels of a motor-vehicle or like wheeled carrier and which is capable vof guick application to the wheels of said vehlc e when occasion recpiires or makes desirable the use of the ra1 s of a railroad-track 1n speedily reaching a certain point ordest1- nation and which attachment may be removed from the wheel without in any manner disarrangin or impairing any part of the wheel for its or inary purposes of a road-ma chine.

The wheel A may be any approved or wellknown formfor instance, such as is commonly used on automobiles or motor-vehicles and employing a rim B, of wood or metal, and a rubber tire C of the pneumatic, cushion, or solid type. It will also have the spokes D and such other accessories, as are usually found associated with such wheels.

The supplemental rim is preferably made of metalsay sheet-steel or thelike-of sufficient thickness to sustain its shape and safely support the weight which it is to carry; This supplementalv rim is adapted to fit over the ordinary rubber tire of the wheel, and it may consist, preferably, of two pieces 10 and 11, the former ofwhich forms the flange and tread of the rim, while the latter is curved transversely to form a se mental band adapted to fit the curvature of the tire and havin such transverse width that it extends around about one-quarter of the tire and closely fits the same. In the drawings I show the segmental band 11 as engaging the circumference of the tire on its outer side, said band having its outer edge portion riveted to the piece 10 at 12 or otherwise firmly secured to said piece.

The piece 10 is made substantially as a flat Patented June 26, 1906.

band, and it encircles the circumference of the tire and the outer edge of the band- 10 and has its central portion rovid'ed with a flange 13, which may be ma e by folding the plate 10 along substantially its longitudinal central line. The straight portion of the band 10 at the side of the flange on which the curved band 11 is. substantially located forms a tread 14, which is adapted to engage and travel on the top surface of the railroadrail, while the flange travels against the side of the head of the rail in the usual" manner to retain the wheel on the rail. of the plate 10 on'the tread side is connected to the segmental band 11 by means of suitable braces 15, riveted tov both arts and spaced at suitable distances aroun the rim. The other transvrselyextending straight portion of the band 10 is' located, preferably,

The outer edge slots 16, which are engaged by the outer ends of the clamp members 17, the connection being in the form of a hin e-joint by reason of the outer end of the 0 amp member being passed through the slot and then curled or bent over the edge of the band 10. The clamp member being thus hingedly connected to the band 10 may be opened and closed, so

to speak, to permit the ready attachmentof the supplemental rim, to be removed when its further immediate use is unnecessary. When closed, as when the attachment is in place on the Wheel, the clamp member extends inward over the inner side of the tire C and its inner rimB and along the spokes a suitable distance. and its inner end is attached to the spokes in some appropriate manner, as by turning over the inner end to an eye or bearing in which is mounted, slidably or otherwise, a transversely-extending rod 20, capable of extending between ad'acent spokes and having its ends curved or bent and adapted to hook bebind the spokes, as shown. It is of course not essential that the locking-rod be slidable or, in fact, that it be a bar, as any well-known means may be employed to secure the inner end of the clamp member without departing from the spirit of my invention.

To attach the supplemental band, as when it is desired to convert the machine froma road-machine to one that will engage and travel on the rails of arailroad-trackfor in stance, when an accident or disaster has occurred at some distant point and it is the desire of the ofiicials or authorities, surgeons, &c., to reach the scene with despatch the band '10'- is'slip ed over the ordinary tire of the wheel unti the segmental band 11 fits closely against'the outer side of said tire. Then the clamp members are closed inwardly over the outer side of the tire and rim to draw the segmental band on the opposite side into close frictional engagement with said tire, and the inner ends of the clamp members are secured to the spokes or otherwise to secure the members and to hold them and the other parts in a secure condition. The machine may now be placed on the rails of the railroad and speeededto its destination with safety and despatch.

In the foregoing description I have disclosed apreferred form of my invention; but

-I do not limit myselftthereto, as reasonable modifications may be made therein Without departing from the spirit or sacrificing any of "the advantages thereof. For instance, in Fig. 4 I show a supplemental tire formed from a rolled strip having the flange 13, the tread 14, and a curved portion 1]., which substantially corresponds/to the curved band 11 of Figs. 1, 2, and 3, and in Fig 5 I show another form, wherein the strip is rolled to form the flange 13 the tread 14 and a curved mem her 11 embracing a portion of the circumference of the permanent tire. Both of these forms are suitably braced, as at 15 and any method may be employed to ho d them in place. The forms shown in Figs. 4 and 5 are made substantially of one piece of sheet-steel or like'material rolled into the form shown.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with a wheel having a permanent tire, of a supplemental tire removably fitting the permanent tire and-comprising two-bands one curved'transversel-y'to fit the curvature of the permanent tireat one side of the vertical center thereof, and the other having a centrally-located flange and oppositely-extending sides, means connecting the curved band with the other band at one side of the flange portion of the latter, and clamp members hinged to the other side of said band and extending inward and attachable to a fixed part of the wheel.

2. The combination with awheel'having a permanent tire, of a supplemental flanged tire removably fitting the permanent tire said flanged tire comprising a band fitting over the permanent tire and having a flange and a tread portion at one side thereof, said flan e and tread portion adapted to fit arail roa -rail, a curved band fixed to the firstnamed band and adapted to fit substantially a side portion of the permanent tire at one side of the vertical center thereof, braces connecting the curved band with the tread portion of the other band, and movable clamp members at the opposite side of the vertical center of the tire adapted to detachably-connect that side of the band with a fixed-part of the wheel whereby the supplemental tire is removably retained in place on the permanent tire.

3. A supplemental tire attachable to the permanent tire of a wheel and comprising a metallic band adapted to circumscribe the tire said band having a projecting flange and a tread portion transverse thereto, and having a rigid curved member adapted to fit substantially a side portion of the permanent tire, and hinged clamp members connecting with the side of the flanged band opposite to the curved band and adapted to detachably hold the supplemental tire in place on the permanent tire.

4. A supplemental tire attachable to the permanent tire of a wheel and comprising a metallic band adapted to-circumscribe the tire said band having a projecting flange and a tread portion transverse thereto, and having a rigid curved member adapted to fit substantially a side portion of the permanent tire, and means connecting with the side of the flanged band opposite to the curved band and adapted to detachably hold the supplemental tire in place on the permanent tire, I my hand in presence of two Subscribing witsaid means comprising clamp members havnesses. ing their outer ends hingedly connected to the band, and means at the inner ends of the mem- CHARLES H.
